Allright, this is valuable information, thanks for that.

Just a small side note: You should also take into consideration where your audience is located.
I post quite a few events taking place in Spain, which are primarily of interest to Europeans, not so much people in the US or China.

I will check if I place them round 17:00 if that makes a difference in number of views.

Of course I also place posts about other stuff, also e.g. how to improve Steemit. I'm going to do a little experiment and copy/paste one of these posts and post that tonight at 01:00. See if that makes a difference.

I'm fortunate that I'm my own boss, working at hours which are most convenient for me, so Steeming in the middle of the night is no problem for me.
